Why Wear a Respirator?

• Protect your health

• Legal – the label is the law

Respirable Health Hazards

• Mists • Vapors • Gases• Molds • Dust• Fumes• Smoke• Aerosols

Alveoli

The Alveoli

The alveoli are where the oxygen from the inhaled air enters your arterial blood, and the carbon dioxide from venous blood goes into the air you exhale.

Any contaminants in the air can enter the bloodstream and be rapidly transported throughout the entire body.

Health Effects

• Acute inhalation effects:

– May burn the entire respiratory tract and lead to pulmonary edema

– May cause breathing difficulties

– May enter blood stream very rapidly upon inhalation and have systemic effects

• Chronic inhalation effects from repeated exposure:

— May lead to the formation of scar tissue.

—This destructs the walls of the alveoli sacs and decreases the area for air to be exchanged.

—Long term effects are definite.

Legality

• You are legally required to follow all personal protective equipment instructions on the label.

• Pesticide labeling lists the minimum personal protective equipment you must wear while handling the pesticide.

• Often the labeling lists different requirements for different activities. Usually more requirements are needed for mixing and loading than for application.

• Handlers performing tasks with liquidcontact potential must wear:

– A half-face respirator with either an organic-vapor removing cartridge with a prefilter approved for pesticides (MSHA/NIOSH approval number prefix TC-23C) or canister approved for pesticides (MSHA/NIOSH approval number prefix TC-14G). See further regulatory requirements in the User Safety Requirements section on this label

Telone* C17

• Handlers performing tasks with no liquid contact potential must wear:

– A half-face respirator with either an organic-vapor removing cartridge with a prefilter approved for pesticides (MSHA/NIOSH approval number prefix TC-23C) or canister approved for pesticides (MSHA/NIOSH approval number prefix TC-14G).

Telone* C17

• Handlers in treated area 1 to 5 days after application must wear:

– A half-face respirator with either an organic-vapor removing cartridge with a prefilter approved for pesticides (MSHA/NIOSH approval number prefix TC-23C) or canister approved for pesticides (MSHA/NIOSH approval number prefix TC-14G).

Telone* C17

• Handlers exposed to high airborne concentrations of this product, such as cleanup, following large spills and exposure to this product in poorly ventilated areas must wear:

– Supplied air respirator with MSHA/NIOSH approval number prefix TC-19C for self-contained breathing apparatus (SCBA) with MSHA/NIOSH approval number prefix TC-13F. See further respirator requirements in the User Safety Requirements section on this label.

– Respirator users must be examined by a qualified medical practitioner to ensure physical ability to safely wear the style of respirator to be worn.

Respirators and Physical Fitness

• Medical evaluations are required for anyone wearing respirators.

• Breathing through a respirator is work for the body.

• Respirators can be hazardous to people with heart or lung problems.

Protect Yourself

When used properly, respirators prevent the inhalation of chemicals and dust and therefore, offer the best protection.

Cartridge

• Air movement is controlled by rubber inhalation

and exhalation valves.

• The adjustable straps are used to keep the respirator snug on the face.

How Respirators Work

When you inhale, air is pulled through the cartridge, where air contaminants are trapped.

How Respirators Work

Respirator Use

Agricultural jobs where respirators are required:

• Handling chemicals (pesticides, disinfectants)

• Nutrient management

• Cleaning grain bins

• Handling moldy hay or silage

• Working in dusty fields

Causes of Pesticide Inhalation

• Breathing vapors,dusts, and mists from handling pesticides

• Using fumigants and other highly toxic pesticides

• Inhaling mists and vapors from pesticide drift

• Working in poorly ventilated spaces

• Using the wrong respirator/cartridge for the job

• Using a poorly fit respirator

• Using cartridges that are spent

Causes of Pesticide Inhalation

Typical Applicator Questions

• I must wear a respirator… which type is best?

• Aren’t they all the same?

• Some look different…does size matter?

• Are there any significant differences?

• Do I really need a fancy one? Won’t a paper dust mask work?

Respirator Maintenance

• Respirators must be cleaned, inspected and maintained regularly.

• Clean in warm soapy water.

• Allow to dry thoroughly before storing or using.

Respiratory Equipment Storage

Protect from:

• contamination

• dust

• sunlight

• extreme temperatures

• moisture

Select an appropriate respirator based on the respiratory hazards to which the worker is exposed, the workplace, and user factors.
